The sea banshee in Greek mythology.
Like mermaids, they have fatal voices that confuse sailors, beautiful and charming female faces, but their bodies are like eagles below their necks. When they see ships passing by, they will fly over and sing beautiful songs. As long as the sailors hear their songs, they will fall into extreme madness, and even jump into the sea to pursue the figure of Sai Ren, and all of them will be buried at the bottom of the sea.
Odysseus, a hero in Greek mythology, in order to listen to Sai Ren's songs with his own ears, tied himself tightly to the mast when his ship passed through the waters haunted by Sai Ren, and then ordered all sailors to cover their ears and only bow their heads and row quickly. Sure enough, Sai Ren appeared, singing the most beautiful melody in the world over and over again around the boat. A few sailors with no ears plugged jumped into the sea madly and were finally caught in the deep sea. Odysseus is also in a state of madness. But for the mast and rope, he would have suffered such a sweet fate. There are many paintings or sculptures of Odysseus listening to Sai Ren's songs in Greek artworks.
However, Sai Ren is different from a mermaid. They won't lure sailors to eat them or rob them of the treasure on board. Besides singing, they won't even hurt sailors. If the sailors were not tempted by singing, they would only return disappointed. The siren that harms human beings for no reason is unique in Greek mythology.
There are other different records in Europe. Some people think that Sai Ren is not the name of a monster, but the name of a magical band (ancient orchestra) on a sea island. They use different musical instruments and play beautiful melodies. The sailors who heard this melody refused to leave, even forgot to eat and sleep, dried up and died on the island. However, such a legend is far less attractive to people than the legend of the eagle-body siren, and gradually disappears through word of mouth.
